The digital portion of the transceiver has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the
FCC
rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment on and off, the user is encouraged to try correct the interference
by performing one or more of the following measures:
- Reorientate or relocate the receiving antenna
- Increase separation between the equipment and receiver
- Connect the equipment to an outlet on a circuit different from that to which the receiver is connected
- Consult the dealer or an experienced radio/TV technician for help.
The ASWipLL system must be installed by professional and experienced technicians who are familiar with
radio frequency (RF) issues such as gains and losses, as well as local building and safety codes. Failure to do
so will void the product warranty and may expose the end user to excessive RF hazard. Regulations regarding
maximum antenna gains, power output and maximum permissible exposure vary from country to country. It is
the responsibility of the customer to operate within the limits of these regulations.
Do not connect the units to the power outlet before mounting the units and completing all communication
cabling, including antennas. Do not connect and disconnect antennas while power is on.
Inherent risks exist in operating equipment in license-exempt bands (i.e. 900 MHz). Airspan recommends that
you do not purchase or deploy any equipment that operates in license-exempt bands without first analyzing
the interference environment at each of your proposed deployment locations. Please contact your Authorized
Airspan System Integrator or Distributor if you have any questions or require assistance regarding interference
analysis. Airspan Networks will not be held responsible for product performance issues related to interference.
In environments that produce disturbances such as paging systems, Airspan recommends using a narrow-
band cavity filter and implementing the appropriate frequency bands (within the filter's capabilities), i.e.
building an NVRAM frequency table using only these frequencies.
Where operators come into direct contact with any piece of electronic hardware, operators must wear an ESD-
preventive wrist strap.
Ensure a minimum 2-meter separation between the outdoor radios and all persons during normal operation,
and a minimum 1-meter separation between adjacently installed ASWipLL outdoor radios.
Mount outdoor radios so that their front panel ports face down to prevent water from settling on the ports. This
avoids damage to the units such as corrosion and electrical short-circuiting.
In accordance with FCC regulations for operating in unlicensed bands, BSR external antennas must provide
EIRP
≤
36 dBm
to prevent interference with other radios operating in the unlicensed band.
Maximum CAT-5 cable length between ASWipLL outdoor radios and indoor equipment is 100 meters.
Enable frequency hopping-based synchronization via the BSDU for multiple BSRs at a Base Station, as well
as synchronization between Base Stations via a GPS (refer to the
ASWipLL Commissioning Manual
).
